Abstract
Disclosed is a slag discharge device of a grinding mill, comprising a slag discharge mouth, a frame body, a slag discharge box, a refiner disc seat and an air inlet. The device is characterized in that the slag discharge mouth is arranged at the outer side of the frame body and is communicated with the slag discharge box; the slag discharge box is fixed in the frame body, the lower end of the slag discharge box is completely sealed; the upper end of the slag discharge box and the upper end of the refiner disc seat in concentric arrangement are formed into a fit clearance, and can rotate relatively; when in operating, the lower end of the air inlet is connected with the air inlet and is also in complete sealing condition; the upper end of the slag discharge box is directly connected with the grinding cavity of the grinding mill; the air inlet is fixed on the outer side of the frame body and is directly connected with the slag discharge box. The soleplate of the slag discharge box inclines and forms an angle which is bigger than or equal to a rest angle of the waste residue; the slag discharge box can stock the waste residue periodically, and the waste residue can be taken away from the slag discharge mouth periodically. The invention removes the scraper, adopts the slag discharge in complete sealing, enlarges the storage space of the slag discharge box, and makes use of the soleplate structure for automatic slag discharging; thus the invention not only saves a great deal of investment, reduces the cost; but also is an extremely reliable slag discharge device of a grinding machine.
Description
(1) technical field
The present invention relates to a kind of grinding machine, especially relate to the slag-draining device in the grinding machine.
(2) background technology
Miller residue discharging device is the important component part of grinding machine, and its effect is that the waste residue that milling chamber internal cause wind can't be held is caught, discharged, and also can be used as the inlet air that enters grinding machine milling chamber simultaneously and distributes passage.At present, common grinding machine discharge device is to adopt and abrasive disk seat one and the synchronous scraper that rotates, and waste residue is scraped to slag-drip opening, enters in the dreg discharging box then.Scraper is installed in the sidewall of the abrasive disk seat that is used to support mill.Because the action request of scraper, can't be need one by the required gap of rotation that forms between dreg discharging box bottom and the abrasive disk seat that rotates with avoiding, thereby also just must bring the problem of two aspects, one of its problem is that scraper just rotates naturally as long as grinding machine rotates, and makes the serious wear of scraper, lost efficacy easily, and the replacing difficulty after losing efficacy, deslagging chamber are blocked full, cause accident easily; Two of its problem is because the existence of above-mentioned rotary gap causes dust, granule waste residue to discharge grinding machine from above-mentioned gap easily, pollutes, and also causes the gap to be strengthened gradually easily, forms vicious circle.The method of head it off all concentrates on shape, the material that changes scraper now, improve in the measures such as sealing means, though these methods can improve the life-span of scraper to a certain extent, improved the sealing effectiveness of dreg discharging box, but but can't change the serious problem of blade wears, the leakage ash phenomenon that also can't avoid occurring has increased installation difficulty and equipment investment simultaneously.
(3) summary of the invention
In order to solve the technical problem that above-mentioned prior art exists, the invention provides a kind of no scraper type miller residue discharging device, this device can realize that not only dreg discharging box seals fully, and has the function of interim storage waste residue and interim deslagging.
The technical scheme that adopts is:
Miller residue discharging device, comprise slag-drip opening, support body, dreg discharging box, abrasive disk seat, air inlet, it is characterized in that described slag-drip opening is arranged in the support body outside, slag-drip opening is communicated with dreg discharging box, dreg discharging box is fixed in the support body, the dreg discharging box lower end seals fully, the dreg discharging box upper end forms fit clearance with the abrasive disk seat upper end of arranged concentric, and can relatively rotate, in the dreg discharging box work lower end except that be in complete sealing state air inlet is connected, the upper end directly links to each other with grinding machine milling chamber, and air inlet is fixed in the outside of support body, directly is connected with dreg discharging box.The dreg discharging box base plate tilts to be the angle of repose more than or equal to waste residue, and dreg discharging box can interimly be stored waste residue, and waste residue can interim taking away from slag-drip opening.
Operation principle: wind enters dreg discharging box by air inlet, and through entering the work of milling chamber after the uniform distribution, in the work, because the waste residue that wind can't be held can fall into dreg discharging box, waste residue slips to slag-drip opening by deadweight along the slag case base plate in the milling chamber.
The invention solves the problem of blade wears, also solved simultaneously gap between dreg discharging box and the abrasive disk seat because of wearing and tearing and made the problem of sealing actual effect, the present invention cancelled scraper, adopt that dreg discharging box is totally-enclosed, the memory space that increases dreg discharging box, utilize the dreg discharging box base arrangement to carry out automatic discharge, not only can save great amount of investment, reduce cost, and be extremely reliable miller residue discharging device.
(4) description of drawings
Fig. 1 is the structural representation of an embodiment of the present invention.
(5) specific embodiment
Please refer to figure one, miller residue discharging device of the present invention, comprise slag-drip opening 1, support body 2, dreg discharging box 3, abrasive disk seat 4, nozzle ring 5, packing seal 6, pressing plate 7, milling chamber 8, mill 9, air inlet 10, slag-drip opening 1 is located at support body 2 outsides, slag-drip opening 1 is communicated with dreg discharging box 3, dreg discharging box 3 is fixed in the support body 2, dreg discharging box 3 lower ends seal fully, nozzle ring 5 is established in exit, dreg discharging box 3 upper end, nozzle ring 5 is with the inboard that fixes on support body 2, and there is pressing plate 7 upper end of nozzle ring 5, and abrasive disk seat 4 upper ends of dreg discharging box 3 upper ends and arranged concentric form fit clearance, and can relatively rotate, gap location is established packing seal 6, abrasive disk seat 4 upper fixed mills 9, and mill 9 tops and support body 2 form milling chamber 8, air inlet 10 is fixed in the outside of support body 2, directly is connected with dreg discharging box 3.Wind enters dreg discharging box 3 by air inlet 10, after process nozzle ring 5 evenly blows out, 8 work in the milling chamber, in the work, the waste residue that can't hold owing to wind in the milling chamber 8 can fall into dreg discharging box 3, waste residue slips to slag-drip opening 1 by deadweight along dreg discharging box 3 base plates and stores, and regularly takes waste residue away from slag-drip opening 1.Its characteristics are dreg discharging box 3 cancellation scrapers, and dreg discharging box 3 lower ends seal fully, waste residue enters dreg discharging box 3 backs and slips to slag-drip opening 1 by deadweight, the base plate of dreg discharging box 3 is in tilted layout, its inclination angle is the angle of repose more than or equal to waste residue, dreg discharging box 3 can interimly be stored waste residue, and waste residue can interim taking away from slag-drip opening 1.
